Monitoring Year 3 Annual Report ‐ FINAL iii
EXECUTIVE SUMMARY
Wildlands Engineering (Wildlands) completed a full‐delivery project for the North Carolina Ecosystem
Enhancement Program (NCEEP) to restore and enhance 6,795 linear feet (LF) of perennial and intermittent
stream channel and to restore and create 9.5 acres (ac) of riparian wetland on a full delivery site in
Catawba County, NC. The project stream reaches consist of UT1, UT1A, UT1B (stream restoration) and
UT1C and UT1D (stream enhancement level II). The project wetland areas consist of RW1 and RW2
(wetland restoration and creation).
The Lyle Creek Mitigation Site, hereafter referred to as the site, is located west of NC Highway 10/ North
Main Street in the Town of Catawba, NC on an active tree farm surrounded by woods and residential land
use (see Figure 1). The site is located in the Catawba River Basin Hydrologic Unit Code (HUC)
03050101140010, and North Carolina Division of Water Resources (NCDWR) Subbasin 03‐08‐32, which is
within a NCEEP Targeted Local Watershed. This HUC qualifies as a service area for an adjacent HUC; as a
result, the Lyle Creek Mitigation Site was submitted for mitigation credit in the Catawba River Basin HUC
03050103. The site is located on one parcel owned by the Garmon Family.
Prior to construction activities, the project streams were regularly modified and maintained and therefore
lacked bedform diversity, habitat, and riparian buffer. The lack of bedform diversity combined with
continued anthropogenic disturbance resulting in degraded aquatic habitat, altered hydrology, and water
quality concerns such as lowered dissolved oxygen levels. The primary goals of the project were to provide
ecological and water quality enhancements to the Catawba River Basin while creating a functional riparian
corridor at the site level, providing wetland habitat and ecological function, and restoring a Piedmont
Bottomland Forest as described by Schafale and Weakley (1990). These goals were achieved by restoring
5,411 LF of perennial and intermittent stream channel and 6.6 ac of wetland area, enhancing 1,384 LF of
intermittent stream channel and creating 2.9 ac of wetland area. Approximately 179 LF of stream was
excluded from the total project credit calculations from crossings (farm roads and power line easements).
Figure 2 and Table 1 present the restoration design for the site.
The following project goals were established to address the effects listed above from project site stressors:
Wetland areas will be disked to increase surface roughness and better capture rainfall which
will improve connection with the water table for groundwater recharge. Adjacent streams will be
stabilized and established with a floodplain connection to promote hydrologic transfer between
wetland and stream;
A channel with riffle‐pool sequences and some rock and wood structures will be created in the
steeper project reaches and a channel with run‐pool sequences and woody debris structures will
be created in the low sloped project reaches for macroinvertebrate and fish habitat. Introduction
of wood including root wads and woody ‘riffles’ along with native stream bank vegetation will
substantially increase habitat value. Gravel areas will be added as appropriate to further diversify
available habitats;
Adjacent buffer areas will be restored by removing invasive vegetation and planting native
vegetation. These areas will be allowed to receive more regular and inundating flows. Riparian
wetland areas will be restored and enhanced to provide wetland habitat;
Sediment input from eroding stream banks will be reduced by installing bioengineering and in‐
stream structures while creating a stable channel form using geomorphic design principles
Construction and planting activities were completed by River Works in April 2012. A Conservation
Easement held by the State of North Carolina has been recorded with the Catawba County Register of
Lyle Creek Mitigation Site
Monitoring Year 3 Annual Report ‐ FINAL iv
Deeds on the 26.62‐acre Lyle Creek project study area within the Garmon parcel. The conservation
easement protects the project area in perpetuity.
Monitoring Year 3 (MY3) monitoring and site visits were completed during May‐June 2014 to assess the
conditions of the project. Except for GWG #6, the site has met the required hydrologic and vegetation
success criteria for MY3. All streams within the site are stable and meeting the MY3 success criteria with
the exception of the discrete location within the upstream portion of UT1A. The site’s overall average
stem density of 405 stems/acre is greater than the 320 stem/acres density required for MY3 and the site
has met the MY5 stream hydrology attainment requirement as all streams have experienced at least two
bankfull events in separate years. All groundwater gages except GWG # 6 met the success criteria for
wetland hydrology.

Section 1: PROJECT OVERVIEW
The Lyle Creek Mitigation Site is a full‐delivery stream and wetland restoration project for the NCEEP in
Catawba County, NC. The Site is located in the Catawba River Basin HUC 03050101140010, and NCDWR
Subbasin 03‐08‐32, which is within a NCEEP Targeted Local Watershed. This HUC qualifies as a service
area for an adjacent HUC; as a result, the Lyle Creek Mitigation Site was submitted for mitigation credit in
the Catawba River Basin HUC 03050103. The Site is located west of NC Highway 10/ North Main Street in
the Town of Catawba, NC, on an active tree farm surrounded by woods and residential land use. The Site
is bounded by Lyle Creek to the north, NC Highway 10/ North Main Street to the east and an elevated
railroad right‐of‐way to the south.
The project stream reaches consist of UT1, UT1A, UT1B (stream restoration) and UT1C and UT1D (stream
enhancement level II). The project wetland areas consist of RW1 and RW2 (wetland restoration and
creation). Mitigation work within the Site included restoring and enhancing 6,795 LF of perennial and
intermittent stream channel and restoring and creating 9.5 ac of riparian wetland. The stream and
wetland areas were planted with native vegetation to improve habitat and protect water quality.
Construction and planting activities were completed by River Works in April 2012. The Site is located on
one parcel owned by the Garmon Family. A Conservation Easement held by the State of North Carolina
has been recorded with the Catawba County Register of Deeds on the 26.62‐acre Lyle Creek project study
area within the Garmon parcel. The conservation easement protects the project area in perpetuity.
Directions and a map of the Site are provided in Figure 1 and project components are illustrated for the
Site in Figure 2.
1.1 Project Goals and Objectives
Prior to construction activities, the project streams were regularly modified and maintained and therefore
lacked bedform diversity, habitat, and riparian buffer. The primary impacts to the project streams were
the result of mowing, ditching, vegetation maintenance, and dredging associated with tree farming
activities. As a result of the aforementioned land activities, the onsite streams were incised and overly
wide with shallow flow. The streams were unable to maintain their channel form and subsequently filled
in with sediment, organic matter, and vegetation. In‐stream bedform diversity was extremely poor and
the longitudinal profile was dominated by shallow runs. The lack of bedform diversity combined with
continued anthropogenic disturbance resulted in degraded aquatic habitat, altered hydrology (related to
loss of floodplain connection and lowered water table), and water quality concerns such as lower
dissolved oxygen levels (due to shallow flow with few re‐aeration points). Table 4 in Appendix 1 and
Tables 10a, 10b, and 10c in Appendix 4 present the pre‐restoration conditions in detail.
The primary goals of the project were to provide ecological and water quality enhancements to the
Catawba River Basin while creating a functional riparian corridor at the site level, providing wetland
habitat and ecological function, and restoring a Piedmont Bottomland Forest as described by Schafale and
Weakley (1990). These goals were achieved by restoring 5,411 LF of perennial and intermittent stream
channel and 6.6 ac of wetland area, enhancing 1,384 LF of intermittent stream channel and creating 2.9
ac of wetland area. Approximately 179 LF of stream crossings (farm roads and power line easements)
were excluded from the total project credit calculations. The Site’s riparian areas were also planted to
stabilize streambanks and wetland areas, improve habitat, and protect water quality. The ecological uplift
can be summarized as starting from tree farming‐impacted streams and wetlands and moving to stable
channels and wetlands in a protected riparian corridor. Restoration of dimension, pattern, and profile
Lyle Creek Mitigation Site
Monitoring Year 3 Annual Report ‐ FINAL 1‐2
was implemented for UT1, UT1A, and UT1B; enhancement of profile and dimension was implemented for
UT1C and UT1D. Wetland restoration and creation included RW1 and RW2. UT1A and UT1B discharge
into an anastomosed wetland complex upstream of their confluence with UT1 as depicted in Figure 2.
This anastomosed wetland complex was not proposed for stream mitigation credit. Figure 2 and Table 1
present the implemented design for the Site.
Monitored enhancements to water quality and ecological processes established in the mitigation plan
(approved 8/2011) are outlined below, followed by expected project benefits which are associated with
restoration, but will not be monitored as part of this project:
Monitored Project Goals
Wetland areas will be disked to increase surface roughness and better capture rainfall which
will improve connection with the water table for groundwater recharge. Adjacent streams will be
stabilized and established with a floodplain elevation to promote hydrologic transfer between
wetland and stream;
A channel with riffle‐pool sequences and some rock and wood structures will be created in the
steeper project reaches and a channel with run‐pool sequences and woody debris structures will
be created in the low sloped project reaches for macroinvertebrate and fish habitat. Introduction
of wood including root wads and woody ‘riffles’ along with native stream bank vegetation will
substantially increase habitat value. Gravel areas will be added as appropriate to further diversify
available habitats;
Adjacent buffer areas will be restored by removing invasive vegetation and planting native
vegetation. These areas will be allowed to receive more regular and inundating flows. Riparian
wetland areas will be restored and enhanced to provide wetland habitat; and
Sediment input from eroding stream banks will be reduced by installing bioengineering and in‐
stream structures while creating a stable channel form using geomorphic design principles.
Expected Project Benefits
Chemical fertilizer and pesticide levels will be decreased by filtering runoff from adjacent tree
farm operations through restored native buffer zones and wetlands. Offsite nutrient input will be
absorbed onsite by filtering flood flows through restored floodplain areas and wetlands, where
flood flows can disperse through native vegetation and be captured in vernal pools. Increased
surface water residency time will provide contact treatment time and groundwater recharge
potential;
Sediment from offsite sources will be captured during bankfull or greater flows by deposition on
restored floodplain areas where native vegetation will slow overland flow velocities;
Restored riffle/step‐pool sequences on the upper reach of UT1A, where distinct points of re‐
aeration can occur, will allow for oxygen levels to be maintained in the perennial reaches. Small
log steps on the upstream portion of UT1B and UT1 Reach 1 Upper will also provide re‐aeration
points; and
Creation of deep pool zones will lower temperature, helping to maintain dissolved oxygen
concentrations. Pools will form below drops on the steeper project reaches and around areas of
woody debris on the low‐sloped project reaches. Establishment and maintenance of riparian
buffers will create long‐term shading of the channel flow to minimize thermal heating.

Monitoring Year 3 Annual Report ‐ FINAL 1‐3
The design streams and wetlands were restored to the appropriate type based on the surrounding
landscape, climate, and natural vegetation communities but also with strong consideration to existing
watershed conditions and trajectory.
The stream restoration success criteria for the Site follows the approved performance criteria presented
in the NCEEP Mitigation Plan Template (version 1.0, 11/20/2009) and the Stream Mitigation Guidelines
issued in April 2003 by the U.S. Army Corps of Engineers (USACE) and NCDWR. Annual monitoring and
quarterly site visits will be conducted to assess the condition of the finished project for five years, or until
success criteria are met. The stream restoration reaches (UT1, UT1A, and UT1B) of the project were
assigned specific performance criteria components for stream morphology, hydrology, and vegetation.
The enhancement reaches (UT1C and UT1D) were documented through photographs and visual
assessments to verify that no significant degradational changes are occurring in the stream channel or
riparian corridor. Monitoring for wetland vegetation will extend seven years beyond completion of
construction. The wetland restoration and creation sections have been assigned specific performance
criteria for hydrology and vegetation. The final mitigation plan was submitted and accepted by the NCEEP
in August 2011. Construction activities were completed by River Works, Inc. in April 2012. Baseline
monitoring (MY0) and as‐built survey was conducted between April and May 2012. Annual monitoring
will be conducted for seven years: stream and vegetation assessment will be conducted for five years and
wetland assessment will be conducted for seven years. The final monitoring activities will be conducted
in 2018 with the close‐out anticipated to commence in 2019 given the success criteria are met. Appendix
1 provides more detailed project activity, history, contact information, and watershed/site background
information for this project.
1.2 Monitoring Year 3 Data Assessment
Annual monitoring and quarterly site visits were conducted during MY3 to assess the condition of the
project. The stream and wetland mitigation success criteria for the Site follow the approved success
criteria presented in the Lyle Mitigation Plan (approved 8/2011).
1.2.1 Vegetative Assessment
Planted woody vegetation is being monitored in accordance with the guidelines and procedures
developed by the Carolina Vegetation Survey‐NCEEP Level 2 Protocol (Lee et al., 2008). A total of 35
vegetation monitoring plots were established during the baseline monitoring within the project easement
areas using a standard 10 meter by 10 meter plot. The final vegetative success criteria will be the survival
of 260 planted stems per acre in the riparian corridor along restored and enhanced reaches at the end of
year five of the monitoring period. The interim measure of vegetative success for the site will be the
survival of at least 320 planted stems per acre at the end of year three of the monitoring period.
The site was re‐planted in late winter 2012 in response to the dead bare roots observed during the MY1
vegetative survey. Most likely, the mortality of planted stems during year 1 was a result of dry soil
conditions, low precipitation, and/or from grass suffocation or crowding of planted stems. The MY2
vegetation survey resulted in an 11% increase in stem presence due to supplemental planting and the re‐
sprout of existing bare roots. After the MY2 vegetation survey an additional supplemental planting was
warranted within the vicinity of plots 4, 6 and 19.
The MY3 vegetative survey was completed in June 2014. The annual vegetation monitoring resulted in
an average planted stem density of 405 stems per acre, which is greater than the interim requirement of
320 stems/acre. Of 35 plots assessed, five did not meet the 320 stems/acre interim requirements and only
one of the five did not meet the year 5 criteria of 260 stems/acre. Total stem densities ranged from 283 –
Lyle Creek Mitigation Site
Monitoring Year 3 Annual Report ‐ FINAL 1‐4
1246 stems per acre with an overall average of 553 stems per acre indicating a strong presence of
volunteer species. Between two and nine native woody species were documented in the vegetation plots
with 22 species present site wide.
1.2.2 Vegetative Areas of Concern
The MY3 vegetation monitoring and visual assessment revealed few vegetation areas of concern, mostly
carrying over from MY2. Invasive species have been identified onsite, including Kudzu (Pueraria lobata),
Johnson grass (Sorghum halepense), and cattails (Typha latifolia). The presence of these species does not
currently appear to be affecting the survivability of planted stems, however, as discussed in the
maintanence plan Wildlands will perform maintenance as needed. Please refer to Appendix 3 for
vegetation summary tables and raw data tables and to Appendix 2 for vegetation plot photographs, the
vegetation condition assessment table and Figures 3.0‐3.3 for the Integrated Current Condition Plan View
which outlines these areas of concern.
Maintenance Plan
The mortality of the bare roots is likely due to crowding or suffocation as early successional weeds and
grasses are rapidly taking hold within the project area. Areas with poor stem survival will be evaluated
during Winter 2014/2015 to determine whether or not supplemental planting will be required. Currently
the invasive species identified on the site do not appear to be negatively affecting planted stems. Visual
assessment will be performed in 2014/2015 to determine if any additional maintenance is necessary to
promote survival of the remaining planted stems. In order to keep the invasive species Kudzu under
control, Wildlands treated the invasive areas around the upstream extents of UT1A and UT1B during the
Fall of 2014 using a glyphosate concentration.
1.2.3 Stream Assessment
Morphological surveys for MY3 were conducted in May 2014. The majority of the streams within the Site
have met the success criteria for MY3 with the exception of a short length of UT1A. Aggradation was
observed along UT1A from station 301+75 to 304+34. This area of concern is further described below.
Aggradation was also observed along UT1B from station 201+46 to 204+75 during the MY3 survey.
Following the survey, a field assessment was completed which showed the sediment load in UT1B had
naturally transported downstream and stream features were functioning as designed. Due to the natural
rehabilitation of the reach there are no reportable areas of concern within UT1B for MY3. Please refer to
Appendix 2 for the visual assessment table, Integrated Current Condition Plan View (CCPV), photographs,
and Appendix 4 for morphological data and plots. It should be noted that the morphological plots in
Appendix 4 show the aggradation in UT1B at the time of survey but do not depict the stream’s natural
rehabilitation condition observed during a follow‐up field assessment.
Surveyed riffle cross‐sections fell within the parameters defined for channels of the appropriate Rogsen
stream type with the exception of cross‐section 9 along UT1A and cross section 12 along UT1B. Both UT1A
and UT1B experienced aggradation from the contributing upstream watershed during MY3. Aggradation
increased in MY3 and has impacted channel flow capacity along UT1A. On May 9, 2014, during MY3, an
additional cross section was installed at station 300+94 on UT1A. This cross section has been installed
upstream of the aggraded section of UT1A to characterize the steeper, upstream section of the reach.
This cross‐section will be monitored within the guidelines presented in the mitigation plan. The
sedimentation in UT1B was observed during the MY3 morphological survey but was not observed during
a site visit in July 2014. Due to the natural rehabilitation of UT1B there are no reportable areas of concern
Lyle Creek Mitigation Site
Monitoring Year 3 Annual Report ‐ FINAL 1‐5
along this reach. In general cross‐sections along UT1 show little to no change in the bankfull area,
maximum depth ratio, or width‐to‐depth ratio.
The surveyed longitudinal profile data for the stream restoration reaches illustrates that the bedform
features are maintaining lateral and vertical stability throughout UT1, and the lower sections of UT1A and
UT1B. In UT1, UT1B and the downstream sections of UT1A the riffles and runs are remaining steeper and
shallower than the pools, while the pools are remaining deeper than the riffles and maintaining flat water
surface slopes. The longitudinal profiles show that the bank height ratios remain very near to 1.0. In the
upper sections of UT1A and UT1B aggradation has occurred due to sedimentation from the contributing
upstream watershed. In the aggraded section of UT1A, the sediment load has extended above the top of
bank. Prior to the morphological survey, UT1B’s riffles and runs had become less steep and deeper than
pools and pools had become steeper and less shallow and resembled meandering riffles or runs (Appendix
4, Longitudinal Profile Plots). Although this data is reported in the appendices, it is not an area of concern
due to the natural rehabilitation of the reach following the transport of the sediment downstream.
At the downstream end of UT1, near the confluence with Lyle Creek, minor aggradation has occurred. This
aggradation is most likely attributed to backwater conditions from Lyle Creek. However due to the
sand/silt nature of the substrate throughout the project, fluctuations in bed elevations were observed
and expected. These fluctuations within UT1 are temporary and seem to typically correspond to storm
events.
In‐stream structures, such as brush mattresses and sod mats used to enhance channel habitat and stability
on the outside bank of meander bends are providing stability and habitat as designed. Pattern data will
be collected in MY5 only if there are indicators from the profile or dimensions that significant geomorphic
adjustments have occurred. No changes were observed during MY3 that indicated a change in the radius
of curvature or channel belt width.
Maintenance Plan
During MY3 aggradation rates increased along UT1A and UT1B. This aggradation is due to upstream bank
erosion and mass wasting occurring upstream of the Site that is outside of the conservation easement.
Wildlands expects UT1A to naturally transform with the input of sediment and will continue monitoring
the aggraded sections to determine if the stream will evacuate the sediment. UT1B will continue to be
monitored for increased sediment loading in future monitoring years.
1.2.4 Hydrology Assessment
At the end of the five‐year monitoring period, two or more bankfull events must have occurred in separate
years within the restoration reaches. During MY3, one or more bankfull or greater events were recorded
on UT1, UT1A and UT1B using a crest gage. Bankfull events were also recorded in previous monitoring
years, therefore, the success criteria has been met for the five‐year monitoring period. Due to high
sedimentation rates on UT1A, the crest gage located at cross section 9 was relocated to station 305+16
on UT1A downstream of the aggraded section of the stream. Please refer to table 14 in Appendix 5 for
hydrologic data.
1.2.5 Wetland Assessment
Ten groundwater monitoring gages were established during the baseline monitoring throughout the
wetland restoration and creation areas. The gages were installed at appropriate locations so that the data
collected will provide an indication of groundwater levels throughout the wetland project area. Historical
growing season data is not available for Catawba County therefore the growing season currently used for
success criteria was applied from nearby Iredell County growing season data. This growing season runs
Lyle Creek Mitigation Site
Monitoring Year 3 Annual Report ‐ FINAL 1‐6
from April 8th to October 27th (202 days). However, additional growing season data are being collected by
two soil temperature loggers that were installed, one within each wetland. These probes will be used to
better define the growing season using the threshold soil temperature of 41 degrees or higher measured
at a depth of 12 inches (USACE, 2010) in subsequent monitoring years. If the probes indicate a longer
growing season than that adapted from Iredell County, the growing season will be adjusted based on on‐
site soil temperature conditions. A barotroll logger and a rain gage were also installed onsite.
All groundwater monitoring gages were downloaded on a quarterly basis and will be maintained on an as
needed basis. The success criteria for wetland hydrology is to have a free groundwater surface within 12
inches of the ground surface for seven percent of the growing season, which is measured on consecutive
days under typical precipitation conditions. All groundwater gages except Groundwater Gage 6 (GWG 6)
met the annual wetland hydrology success criteria for MY3. Please refer to Appendix 2 for the
groundwater gage locations and Appendix 5 for groundwater hydrology data and plots.
1.2.6 Benthic Macroinvertebrate Assessment
Prior to site construction, three macroinvertebrate assessment locations were established at the Lyle
Creek Mitigation Site (UT1 Upper Reach, UT1 Lower Reach and UT1B) as shown on Figure 3. These sites
were sampled before construction (December 2011) and during MY‐2 (January 2014). Sampling was
conducted using the Standard Qualitative Method (Qual 4) in compliance with the North Carolina Rapid
Bioassessment Standard Operating Procedures for Benthic Macroinvertebrates set by NCDENR (2012).
Samples were assessed and identified at the species level by Pennington & Associates, Inc. Sampling
results show Ephemeroptera + Plecoptera + Trichoptera (EPT) taxa richness increased from pre‐
construction (Poor) to post‐construction (Fair) on UT1 Lower and UT1B. ETB richness scores on UT1 lower
increased from 1 to 12 from pre‐construction to MY2 while UT1b increased from 6 to 7 between pre‐
construction and MY2. EPT taxa richness along UT1 Upper remained fair between pre‐ and post‐
construction with a richness score of 13 during pre‐construction and 12 during MY2. The NC Biotic Index
improved for all sampling locations showing pollutant intolerant bugs have become more abundant across
the site. UT1 upper improved from 5.76 to 4.27, UT1 lower improved from 7.06 to 6.26, and UT1B
improved from 7.67 to 6.13.
1.3 Monitoring Year 3 Summary
With the exception of a short reach within the upstream portions of UT1A, the streams within the Site are
stable and functioning as designed. The average stem density for the Site is on track to meet the MY5
success criteria; however, a portion of the individual vegetation plots did not meet the current success
criteria as noted in the Integrated Current Condition Plan View map. A vegetation maintenance plan will
be implemented in late winter 2014/2015 to determine whether or not supplemental plantings will be
warranted for the portions of the site with low stem density. There have been three bankfull events
recorded in separate monitoring years along each restored project reach since construction commenced;
therefore, the Site has met the MY5 stream hydrology attainment requirement. All groundwater gages
with the exception of GWG 6 met the wetland hydrology success criteria for MY3.
Summary information and data related to the performance of various project and monitoring elements
can be found in the tables and figures in the report appendices. Narrative background and supporting
information formerly found in these reports can be found in the Mitigation Plan documents available on
NCEEP’s website. All raw data supporting the tables and figures in the appendices are available from
NCEEP upon request.

Section 2: METHODOLOGY
Geomorphic data was collected following the standards outlined in The Stream Channel Reference Site:
An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in the Stream Restoration: A Natural
Channel Design Handbook (Doll et al., 2003). Longitudinal and cross‐sectional data were collected using
a total station and were georeferenced. All Integrated Current Condition Plan View mapping was recorded
using a Trimble handheld GPS with sub‐meter accuracy and processed using was Pathfinder and ArcView.
Crest gages were installed in surveyed riffle cross‐sections and monitored quarterly. Hydrology
attainment installation and monitoring methods are in accordance with the USACE (2003) standards.
Vegetation monitoring protocols followed the Carolina Vegetation Survey‐NCEEP Level 2 Protocol (Lee et
al., 2008).

EEP Targeted Local Watershed
The subject project site is an environmental restoration site of the
NCDENR Ecoysystem Enhancement Program (EEP) and is
encompassed by a recorded conservation easement, but is
bordered by land under private ownership. Accessing the site may
require traversing areas near or along the easement boundary and
therefore access by the general public is not permitted. Access by
authorized personnel of state and federal agencies or their
designees/contractors involved in the development, oversight,
and stewardship of the restoration site is permitted within the terms
and timeframes of their defined roles. Any intended site visitation or
activity by any person outside of these previously sanctioned roles
and activites requires prior coordination with EEP.
Directions:
From I-40 exit 138, follow
Oxford School Road south
for 2.2 miles. Oxford School
Road becomes North Main
Street (NC Highway 10) after
a bridge crossing at Lyle Creek.
From North Main Street, turn
right onto 3rd Avenue NW.
Follow 3rd Avenue NW around
and to the right to approach the
Catawba Tree Farm gate.
